Isaiah 2 isn't about the Messias 2nd coming. It's about his earthly ministry, which is still going on,
But ye are come unto mount Sion, and unto the city of the living God, the heavenly Jerusalem Heb.12:22 (The mountain of the Lords house),
Unbelievers cannot see it, or can they enter it unless they are born again.
The purpose of dismantling human weapons is to acknowledge their uselessness. Their uselessness is proven by the resurrection of our Lord. And as I told you, only those who recognize the mountain of the Lords house beat their weapons into plow blades. Jesus is not returning to unite all of mankind, or to have all of mankind experience the peace and safety of his rulership. Those things are available to people now.
If you are born again, you understand this world isn't ruling over you. You rule over it in the love of our sweet Savior
You're spiritualizing and taking passages out of context. All prophecies go back to the covenant promise, which is "that the Almighty's nation of priests will spread the knowledge of the Living God to the nations of the world, and as an effect the nations will enter into peace (the evidence of which is dismantling of weapons)".
Two groups involved:
A) "Israel", the nation of priests (made up of Jew and gentile believers)
B) the nations (made up of gentiles) who are ignorant of the Almighty
The Almighty's 1st step is to form His nation by drawing in those who are His from the nations; those who overcome the world and its temptations...
we're still within this 1st step.
The 2nd step is for his priests to teach the nations His ways...which begins during the millennium. This is why
half of all OT prophecies have yet to be fulfilled.
It is Almighty's will that none should perish but come to the knowledge of the truth (
2 Peter 3:8-10). There are many people who honestly don't know the truth because those who have (supposedly) represented the Almighty throughout the centuries have done unspeakable evil in His name. So the world was left to its own devices - vanity - until the "sons of God" manifest in the world (
Romans 8:19).
There are people who are genuinely unsure of the existence of the Living God who - like Thomas - need to see for themselves. They will see, but those who do not need to see are called "blessed" (
John 20:29). And there are those who - because of lies and mistreatment by those who supposedly represent God - are atheistic, who will be judged based on how they followed their conscience (
Romans 2:12-14). The Almighty isn't cruel as to destroy the ignorant without giving all a chance to walk in truth.

Folks are missing half the plan if they think the story is over when the Messiah appears to gathers them. When He comes, Israel (jew & gentile believers) finally reaches it's intended
starting point to fulfill the Almighty's purpose for them (before Israel sinned, was scattered, and needed to be redeemed & restored).
The Almighty's word will not come back void (
Isaiah 55:11). He
said Israel will be His priests to reconcile the world to Himself. It'll only take a "day" (i.e. a thousand years) to remove the iniquity (
Zechariah 3:9). This is why satan is bound, so that there will be no deception. No leaven. No confusing myriad of interpretations. Pure truth.
Only when all know the truth will they have a real choice to walk in it or reject Him and if they choose the latter (and many will, unfortunately) then they will be wiped out in fervent heat along with their father.
